Over two months, contributed to the xchainjs-lib repository by delivering six features and resolving four bugs focused on blockchain client reliability, security, and developer experience. Work included adding Ledger hardware wallet support for the Arbitrum client, implementing a critical security patch, and modernizing the Radix client with a lightweight gateway API. Enhanced EVM client approval flows and introduced Solana RPC transaction pagination to improve data accessibility. Used TypeScript and JavaScript to refactor code, improve error handling, and streamline dependency management. Prioritized code quality, security best practices, and maintainability, resulting in faster, more resilient clients and smoother workflows for developers and users.
